Fleet Sizing and Charger Allocation in Electric Vehicle Sharing Systems
Yuntian Deng, Abhishek Gupta, Ness B. Shroff
In this paper, we propose a closed queueing network model for performance analysis of electric vehicle sharing systems with a certain number of chargers in each neighborhood. Depen…
ByGARS: Byzantine SGD with Arbitrary Number of Attackers
Jayanth Regatti, Hao Chen, Abhishek Gupta
We propose two novel stochastic gradient descent algorithms, ByGARS and ByGARS++, for distributed machine learning in the presence of any number of Byzantine adversaries. In these…
Steady-state fluctuations of a genetic feedback loop with fluctuating rate parameters using the unified colored noise approximation
James Holehouse, Abhishek Gupta, Ramon Grima
A common model of stochastic auto-regulatory gene expression describes promoter switching via cooperative protein binding, effective protein production in the active state and dilu…
Convergence of Recursive Stochastic Algorithms using Wasserstein Divergence
Abhishek Gupta, William B. Haskell
This paper develops a unified framework, based on iterated random operator theory, to analyze the convergence of constant stepsize recursive stochastic algorithms (RSAs). RSAs use…
Learning in Markov Decision Processes under Constraints
Rahul Singh, Abhishek Gupta, Ness B. Shroff
We consider reinforcement learning (RL) in Markov Decision Processes in which an agent repeatedly interacts with an environment that is modeled by a controlled Markov process. At e…
